I just want to know what you did to burn so many calories! (I heard that highly active sex can burn upto 750 calories per hour!!)
Just Kidding! Joking aside, here is a trick I learnt for parties and diet ruining events. Just work off in advance the calories you are going to consume. I have a low calorie breakfast, lunch etc. (
E.g eggs for breakfast, no toast. Chicken and salad for Lunch)
Round it off with some high cal burning exercise (like your 1001 cal one!) and you will balance off the evening without too much guilt.
